Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The project online method and the project online device provided by the embodiment of the invention utilize the resource pool technology to deploy the mirror image of the new version project in the resource pool of the distributed computer cluster, so that the two mirror images of different versions of the same project exist in the resource pool and operate simultaneously; and after detecting that the new version project task is normally executed, increasing the number of the project mirror image execution tasks of the new version in the resource pool until the number of the project mirror image execution tasks of the new version in the resource pool reaches a preset threshold value, and distributing all the tasks received again to the project mirror image execution of the new version in the resource pool to finish the on-line of the project. Therefore, by applying the embodiment of the invention, the server does not need to be removed from the computer cluster, and the process of online new version items is simplified.
Referring to fig. 1, a process of the project online method according to the embodiment of the present invention is applied to a distributed computer cluster, and includes:
step 101, deploying the mirror image of the new version project in a resource pool of the distributed computer cluster, so that two different versions of the mirror image of the same project exist and operate in the resource pool at the same time. I.e., both the grayscale version and the online version of the same project exist and run in the resource pool.
In this step, the docker application container engine may be utilized to deploy the mirror image of the new version project in the resource pool, and isolate the new version project from the online version project in the resource pool, so that two different versions of the same project exist and run in the same resource pool at the same time.
Specifically, in this embodiment, a docker application container engine may be used to generate and store a docker image corresponding to a new version of an item according to a code of the new version of the item; then, after an item version updating instruction is received, pulling a docker mirror image of the new version item from the stored docker mirror image; and finally, deploying the docker mirror image of the pulled new version project in the resource pool to realize the isolation of the new version project in the resource pool and the online version project.
The generating and storing of the docker image corresponding to the version item may specifically include: compiling a docker file for the new version item code, generating a docker image (docker mirror image) belonging to the version item, distributing a corresponding tag number, and correspondingly storing the tag number of the docker image and corresponding information of the version item in a database or other distributed storage media of the distributed computer cluster. As can be understood by those skilled in the art, when the gray level of the project codes of all versions is on line, the docker images of the corresponding version projects are generated and stored.
And 102, distributing one part of the newly received task to be executed to the online version project mirror image execution in the resource pool, and distributing the other part to the new version project mirror image execution in the resource pool.
In this embodiment, the amount of tasks to be executed by the new version project image and the amount of tasks to be executed by the online version project image may be determined from the tasks to be executed, and the new version project task and the online version project task, that is, the grayscale project task and the online project task, may be generated; and then, distributing the new version project task and the online version project task to different computing nodes in the resource pool for execution by using the distributed computing framework. The specific process of distribution by using a distributed computing framework belongs to the prior art. In the embodiment of the invention, project tasks of different versions are distributed to different computing nodes in a resource pool by using a distributed computing framework.
In practical application, a new version item image and an online version item image may be selected from the stored docker images. And determining the amount of tasks to be executed by the new version project image and the amount of business to be executed by the online version project image from the tasks to be executed, and generating a gray online project task and an online version project task. And storing the task information of the generated gray level online project task and the online version project task to facilitate the adjustment of subsequent task quantity, and rapidly adjusting each project version or task quantity when problems occur, thereby realizing the backspacing of gray level. The task information of the gray level online project task and the online version project task at least comprises the following steps: tag numbers of project images of tasks to be executed and the quantity of tasks with different versions for executing the tasks.
And then, distributing the gray level online project task and the online version project task to different computing nodes in the resource pool to be executed by using a distributed computing framework. And each computing node executes the gray level online project task or the online version project task according to the tag number and the task quantity in the task information of the gray level online project task or the online version project task.
And 103, detecting whether the project image execution task of the new version in the resource pool is normal.
In practical applications, the specific detection method may be the same as that in the prior art, and is not described herein again.
And 104, if so, increasing the number of the project mirror image execution tasks of the new version in the resource pool, and after the tasks are executed, continuing to execute the operation step of detecting whether the project mirror image execution tasks of the new version in the resource pool are normal or not until the number of the project mirror image execution tasks of the new version in the resource pool reaches a preset threshold value, then distributing all the tasks received again to the project mirror image execution of the new version in the resource pool, and completing the online of the project.
In this step, the number of the project mirror image execution tasks of the new version in the resource pool is increased under the condition that the project mirror image execution tasks of the new version, namely the gray level online project tasks, are normally executed. And when the task quantity of the gray level online project task reaches a preset threshold value, determining that the gray level online is stable, and allocating all the re-received tasks to the project mirror image execution of the new version in the resource pool to complete the online of the project.
In practical application, the task amount of the project mirror image execution task of the new version can be gradually increased according to a preset rule. For example: firstly, 10% of tasks to be executed are distributed to the project mirror image of the new version, after the tasks are executed normally, 10% of tasks to be executed are added to the project mirror image of the new version, and after the tasks are executed normally, 10% of tasks to be executed are added; and repeatedly executing until 90%, determining that the gray level is stable, and distributing all the re-received tasks to the project mirror image execution of the new version in the resource pool, namely completing the project line-up.
In other embodiments, in the event that it is detected that a new version of the project image in the resource pool is not performing properly, the method further comprises: and distributing the re-received tasks to be executed to the online version project mirror image in the resource pool for execution, and deleting the mirror image of the new version project in the resource pool. I.e. to achieve a grey scale back-off.
In practical application, all the re-received tasks to be executed can be directly allocated to the project mirror image of the online version in the resource pool for execution, the mirror image of the project of the new version in the resource pool is deleted, and rollback is completed.
Step-wise fallback is also possible, for example: when 50% of the tasks to be executed are allocated to the project image of the new version and 50% of the tasks to be executed are allocated to the project image of the online version, if it is detected that the tasks are not normally executed, the ratio may be reduced, for example, adjusted to 40% of the tasks to be executed are allocated to the project image of the new version and 60% of the tasks to be executed are allocated to the project image of the online version. If the execution is still not normal, reducing the tasks to be executed by 10% and distributing the tasks to be executed to the project mirror image of the new version, if the execution is still abnormal, reducing the tasks to be executed by 10% and distributing the tasks to be executed to the project mirror image of the new version, repeatedly executing the tasks until all the tasks to be executed are distributed to the project mirror image of the online version, deleting the mirror image of the project of the new version in the resource pool, and finishing rollback.
As can be seen from the above embodiments, by applying the embodiments of the present invention, the server does not need to be removed from the computer cluster, and the process of online new version items is simplified.
